I see that the two very useful commands Quick search and Find in drafts list are in the menu bar item of Drafts - but there are no global shortcuts to invoke them when drafts is in the background or minimised (that I could easily find for them).
I would find that useful, especially the Quick Search.
Any plans to add to Draft general preference shortcuts these two items?
No plans for a global key, but you could create your own with many launcher/utility apps. Drafts has URL schemes to open directly to both those places:
drafts://quickSearch
drafts://search
You could setup a shortcut in Keyboard Maestro, Better Touch Tool, or other similar automation apps that open those URLs and support configuring global shortcuts for their actions.
